Phabricator updated HBASE-4742:
-------------------------------
Attachment: D237.1.patch
Liyin requested code review of "[jira] [HBASE-4742] Split dead server's log in
parallel".
Reviewers: Kannan, khemani, Karthik, mbautin, JIRA
When one region server goes down, the master will shutdown the region server
and split its log.
However, splitting log is a blocking call and it would take some time.
If more than one region server go down, the master will split its log one by
one, which is not efficient.
Since we have the distributed log split, we could split these logs from the
dead servers in parallel.
TEST PLAN
1) add one unit test for multiple region server shut down case
2) running all the unit test
3) will test it in dev cluster
